Soooo how bad is it to red line an old Boxster?

158K miles is a lot of miles. Your engine is definitely a senior citizen.

Your current driving style will have very little to do with the remaining longevity of the engine. What matters the most is how it was treated the previous 158K miles. If the engine was hammered on for years and years, driving calmly now won't matter much as whatever wear it experienced can't be undone. And if it was driven by a little old lady who never revved it over 3K rpm, then an occasional run up to redline isn't going to matter much.

My advice is to enjoy it and if that means the occasional run up to redline, then so be it.

Starting with a used 90K mile engine, my engines experience more than 3,000 runs up to redline each year on the race track (4 upshifts per lap x 10 laps x 4 sessions x 20 days). At this level of use (abuse?), an engine lasts 2 years. Then I install another used engine and keep going. I'm on Engine #5.

Wow....sounds like your having a blast on the track with these little monsters. I am sure you know then inside and out by now. Yes I feel like I am on borrowed time but just want to enjoy the car for the summer or maybe even a couple of years. If she blows up then she blows up. At that time she would get a nice used replacement and we will keep the ole gal rollin.

It'll make for a great story blowing er up in a spirited drive than blowin er up in granny gear.

Redline upshift on a straight road, no problem.

Redline mid corner on a long sweeper, or over-rev downshift is the motor killer.

Enjoy your car!
